BOX-GIRDER CONSTRUCTION FOR CAR BODIES.

The present invention relates to dump cars The car bottom, 11, isprovided with a in general and principally to that class of flat bottom, 13, and upwardly and outwardly 'cars used in connection with quarry operadiverging bottom portions or side plates, 14, tions. All quarry cars when used for steam terminating at their outer edges in right 5 shovel service are subjected to tremendous angular bent portions or ledges, 15, as is shocks and strains.

This downwardly and in- My invention in the form or embodiments wardly bent portion, 24, it will be noted, is

' indicated, generally, as at 12. the same distance as the thickness of the supporting beams, 16, so that the end of the supporting beams may be snugly fitted therebetween.

In the form of the box-girder construction illustrated in Figure 4, the side plate, 14, terminates at the outer end of the supporting beam, 16, to which it is, of course,

riveted. In this instance I employ-a pair of angle members, 25 and 26, whose spaced edges or legs, 27 and 28, are riveted tothe side plate, 14, as shown at 29, and the opposite edges of the supporting beams, 16, also riveted as indicated at 30, Whereas the portions or legs, 31, of the angles, 25 and 26, are riveted at 32. In this embodiment it will be noted that the transverse end of the box-girder is formed of two thicknesses of metal by reason of the pair of members or legs, 31, and in this respect is similar to the first described form of my invention.

This construction, it will now be readily.

seen, affords a very rigid and substantial support for the entire body of the car and effectually prevents any twisting, bulging or straining of the body with respect to the main frame support; all possibility of bulging or bowing down or out of any part of the side Walls or box-girder construction being therefore eliminated.

What I claim is:

1. A reinforcing edge for metallic car bodies comprising, a plurality of transversely spaced supporting beams, each of said beams extending completely along the bottom and sides of the car, conforming to the contour thereof and secured thereto, the outer edge of said body being provided with a transverse and outwardly extending member integrally formed wit-h respect thereto and extending the substantial distance of the thickness of said supporting beams and further provided with an integrally formed and downwardly bent portion and means for securing it to said supporting beams.

2. In a metallic car body, a reinforcing edge adapted to extend lengthwise of the car, and comprising, a plurality of vertically spaced supporting" beams extending completel y around the outer side of the body and conforming to the contour thereof, the upper end of said body being provided with a transverse and outwardly extending ledge integral with said upper end, the ledge extending transversely the substantial distance of the thickness of said supporting beams, said member being further provided with an integrally formed and backwardly bent angular portion, and means for securing said reinforcing ledge to the supporting beams.

3. A reinforcing edge for metallic car bodies comprising, a plurality of transversely extending and spaced sup orting beams conforming to the contour o the body securely mounted to the outer side thereof, the outer edge of said body being provided with an outwardly extending and right angular ledge, said ledge being integrally formed with respect to the adjacent portion of the 1 car body, the transverse length of the ledge being substantially the same distance as the thickness of the supporting beams, said right angular ledge bein further providedwith an integrally forme and backwardly extending right angular leg adapted to bear against the adjacent portion of said supporting beams, and means for securing the leg to said supporting means.

4. A reinforcing edge for metallic car bodies comprising, a plurality of vertically spaced and transversely extending supporting beams secured to the outer side of the body and conforming to the contour thereof, and a substantially U-shaped reinforcing edge extending lengthwise of the body adapted to snugly fit a portion of the ends of said supporting beams and riveted thereto.
